Ipsedixitism is the
pejorative term for an unsupported
rhetorical assertion; it is a term in
logic for a missing argument. An ipsedixitism is not explicitly defined as an
axiom, and certainly not as a
premise, but often appears as such in a
syllogism like: "The economy needs more scientists, so expansion of science education will boost the future economy". The
proposition rests on an ipsedixitism unless reasons are given that the "economy needs more scientists".
